new and useful Improvements in Clamps, of

which the following is a specification.

This invention relates to clamps, and particularly to clamps for bands which are drawn tightly around cylindrical washing receptacles or tubs and the like.

The object of this invention is to provide a simple and improvel clamp for bands adapted to meet the requirements of the use to which it is subjected.

Generally speaking, this and other objects are accomplished by providing a clamp for connecting the ends of a band, including duplicate members secured to the ends of the band, each member having an end receiving loop, and means connecting said members for changing their relative position for tightening or loosening the band.

The invention is illustrated on the accompanying sheet of drawings, in which- Figure 1 is a fragmentary sectional view of a cylindrical tub showing my clamp applied to a band encircling the tub;

Fig. 2 is a front elevation of one of the members forming my clamp;

Fig. 3 is a side elevation of the same; and,

Fig. 4 is an enlarged sectional view showing the cooperative association between the end of the band and the clamping members.

Bands have been adjustably secured around cylindrical receptacles of a washing machine, and also around other devices and receptacles. The means for tightening and loosening these bands have taken various shapes. In my particular clamp for the purpose indicated, I have provided a novel arrangement which is adapted for success ful commercial usage.

Reference being had to the drawings, it will be noted that I have shown my invention in connection with a cylindrical receptacle, including a plurality of members 10 which are connected by suitable joints 11, a band 12 encircling the receptacle for the purpose of holding the members 10 in such relation with respect to each other as to prevent leakage of water or the like from the cylindrical member or tub. The clamp for drawing the ends of the band together include preferably two duplicate interchangeable members 13, each of which has a loop portion 14: in which is receivedthe bent-backend portion 15 of the band 12.

Each of'the clamping members 13 also has a groove 16 in the under side thereof, and it will be noted that said groove is tapered so that the band 12 may rest completely therein, while at the same time the band engages the periphery of the cylindrical member; The band 12 near its ends is provided with portions 17 which extend outwardly from the cylindrical member and have apertures 18 through which passes a threaded member 19, which'also extends through apertures 20 within the members 13 and which are in alinement with the openings 18 in the band 12. This threaded member 19 extends in a straight line and connects the ends of the band with the cooperation of the clamping members 13. Nuts 21 are threaded onto the outer ends of the threaded member 19 and engage the rear walls of the clamping members 13. These nuts may be drawn up to any desirable degree to tighten the band 12 the desired amount. Likewise, the band may be loosened by turning the nuts 21 in -an opposite direction.

In connecting the parts, it is merely necessary to slip each of the clamp members 13 onto the ends of the band 12 in such a man ner that the back-turned portions 15 thereof pass into the loops 14 and the main part of the band rests in the grooves 16 in the bottom of the clamping members. These grooves 16 are made at such an angle with respect to the apertures 20 as to overcome any tilting action of the members 13 about the inner front corner or edge 22 thereof. In this way the clamping action is made secure and can be depended upon. The openings of the loops 14 of the clamping members preferably are in communication with the apertures 20 to make each of said mem-' bers 13 as light as possible.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims,

I claim:

1. A clamp for operatively connecting the ends of a band which has its ends turned ends of a band which has its ends turnedback forming loops, including duplicate members secured to the ends of the band, each member having an end receiving loop and an aperture, said aperture being positioned between the loop and the band, and means extending through the apertures connecting said members for changing their relative positions for varying the tension of the band.

3. A clamp for operatively connecting the cndsof a band which has its ends turned back forming loops, including duplicate members secured to the ends of the band, each member having an end receiving loop, a band-receiving groove and an aperture, said aperture being positioned between the loop and the band, and means extending through said apertures connecting said back forming loops, including a member having an end recelving loop, an aperture and a band seatlng groove, said aperture being positioned between the loop'and the band, 1e groove and aperture being at an angle wlth respect to each other to prevent a turning movement of said member when the clamp is tightened.

5. As a new article of manufacture, a clamp member having a band-receiving loop, an aperture for an adjusting bolt, and a groove for seating a band, said loop being 011 the opposite side of the clamp from the band-seating groove. I

6. As a new article of manufacture, a clamp member having a band-receivingloop, an aperture for an adjusting bolt, and a groove for seating the band extending at an angle with respect to said aperture, said loop being on the opposite side of the clamp from the band-seating groove. f
